.To all whom it may concern:

; Be it known that we, Ounrrs A. Souinns and ALBERT E. HUMPHREY, citizens Off the United States, residing at Lyndonville, in the county of Caledonia and State of Von mont, have invented certain new and useful Improvements in Door-Hangers, of which thefollowing is a specification.

The present invention relates to. an improved device for the mounting of sliding doors, and is especially designed for use in connection with the doors upon freight-cars or other doors where the tracks are exposed and are liable to become obstructed by dethe merits thereof and also to acquire av knowledge of the details of construction of the means for effecting the result referenceis to be had to the following description and accompanying drawings, in which Figure 1 is a side View of'a portion of a car and shows a door mounted in accordance with my inventibn. Fig/i is a transverse sectional view through the upper portion of door. Fig. 3 is a detail perspective view of the track, and 4 is a similar view of the hanger.

Corresponding and like parts are referred to in the following description and indicated in all the views of the drawings by the same reference characters.

The numeral 1 design ates the side of a car, and 2- the door, which maybe constructcddn any suitable manner. The track 3 is secured to the side of the car immediately over the door-opening and is of such a length as to extend to on of the door for distance equal to the width thereof. This track 3 comprises, essentially, two flanges wh ch are disposed at" approximately right angles to each other. One of the flanges is employed in securing the track to the can-while the opposite flange 5 projects outwardly and hasgapproximately the form of a Vshaped trough. This trough is formed with two oppositely-inclined sides and is provided along its base at suitable intervals with a series of openings 6. It will. thus be seen that any cinder-s or dirt which may fall upon the track will be deflected to the bottom thereof by means of the inclined sides and will finally escape through the openings 6; :This feature-is particularly valuable where the device is used upon railroad-cars, since they are exposed to conditions very favorable for the collection of tandem. The hangers 7 are somewhat similar in construction to the track 3, and one of them is preferably se cured to each end. of the door, as shown in the drawings. These hangers comprise two flanges at approximately right angles to each other, one of which, 8, is secured to the outside face of the door, While the opposite flange 9 projects inwardly and has the form of an inverted-V-sha ed trough. The ends of these troughs are c osed at 10,-anda number of balls 11 are located between the troughs and the track 3. Owing to the fact that the hangers and the track are both '80 formed with angular troughs within which the balls 11 operate, it will be apparent that the amount of friction will be reduced to a minimum, since each of the balls can come into contact with either the hanger or the trough at only two points, and the surface of contact when the door is operated will be two minor circles upon the balls. This construction lies the double advantage of reducing the friction to a very small amount and also of preventing the accumulation of cinders or dirt in the track.

Having thusdescribed the invention, what is claimed as new is I 1. 'lnadevice f-the character described,

the combination o a track in the form ofa V- shaped tro11gh,fsa'1d trough being provided with a series of openings in its under side,

means for supporting the track, a door, a I

hanger secured to the door and comprising an inverted-\l-shaped trough located over the track, and a series of balls interposed be -J tween the hanger and the track.

2. In a device of the character described,

the combination of a track comprising twoy 1o 5 secure the track in position while the oppo- Patented Novlfi, ieoe.

site flange is in the form of a V-shaped inwardly over the track, and a series of balls trough,.said trough being provided withaseinterposed between the hangers and the ries of openings inits under side, means for track. supporting the track, a sliding door, a hanger In testimony whereof We afiix our signa- 5 at each end of the sliding door, said hangers tures in presence of two Witnesses.

comprising two flanges at approximately CURTIS A. SQUIRES. [1,. s] right angles to each other, one of the flanges ALBERT E. HUMPHREY. [n s] being secured to the door, While the opposite Witnesses: flange is in the form of an inverted-\I-shaped RODNEY COBURN,

1o trough having its ends closed and projecting I E. M. CAMPBELL.
